1. I usually work with something around 3000 x 3000 if I'm not working on something that I'll want to print later. It that's the case I'll use 5000 x 5000 or 6000 x 6000 at least. 2. 300dpi so it's good for printing. I always use that otherwise I forget to change it when I need it. 3. For the sketch and the lines in the beginning I use a different brush but what you use here doesn't really matter. For the rest of the painting I use the same one. A square one with a slight texture to it. I made mine myself but it is something like the 12th one from the top in the left row of this set: sakimichan.deviantart.com/art/… (it was the closest one I could find and right now I can't upload the brush I have)
That's awesome!! Thank you so much for getting back to me! Again I REALLY Love your human portraits I hope to paint like that someday! haha. Right now not getting much practice but it'll happen someday xD
Not really, I haven't used anything like that myself. I just study the photo to figure out the tones and what sort of light the picture have then I just guess my way forward. If I have a certain tone I need but can't find on my own I just might cheat and use the colour-picker. But by doing that you make yourself a disfavor (or what I should call it). The best is to struggle through and then suddenly you're a pro at picking out colours by just looking at them. (I'm not saying I am though, haha) Anyway, good luck!
